I have a few large choppers. I wouldn't want to use the bigger ones, like my Rat Daddy and HI ASTK , for machete work. I think my Basic 11 and CS Gurkha Kukri are light enough for clearing vines but still heavy enough to use for chopping. They are definitely a compromise, but I'm okay with that.
Oh, and my SS4 and CABS make good companion blades.
